Segway-The Human Transporter

The Segway Human Transporter is one of several low-speed transportation devices (e.g., bikes, scooters, wheelchairs) that, under certain circumstances, travels on sidewalks, roadways, and other shared-use paths. The objective of this research was to examine the primary operating characteristics of the Segway. In this thesis, we designed and constructed mechanically based system for a two wheel balancing Segway robot. In this paper we present a Segway based on gyro sensor, accelerometer along with a microcontroller and use of mechanical and electrical hardware’s. The dynamics of the vehicle is similar to the classical control problem of an inverted pendulum, which means that it is unstable and prone to tip over. This is prevented by electronics sensing the pitch angle and its time derivative, controlling the motors to keep the vehicle balancing. This kind of vehicle is interesting since it contains a lot of technology relevant to an eco-friendly and energy efficient transportation industry. This thesis describes the development of a similar vehicle from scratch, incorporating every phase from literature study to planning, design, vehicle construction and verification. The main objective was to build a vehicle capable of transporting a person weighing up to 70-80 kg and capable of travelling to some km distance with varying speed. The rider controls are supposed to be natural movements; leaning forwards or backwards in combination with tilting the handlebar sideways should be the only rider input required to ride the vehicle. This thesis also take into consideration the material used with minimum possible cost. The design of Segway Human Transporter is such that it covers less space and comfort to the user.
